Feature / gpt-6-astra / v1/responses
Added Ultrafast mode for GPT-6 Astra in the Responses API. Use gpt-6-astra with service_tier: "ultrafast" to reduce the time between generated output tokens. It is available to API customers, subject to rate limits, with global processing and US data residency. EU and other regional inference residency aren't supported. See Ultrafast pricing.
公式の更新履歴を見る ↗Fix / gpt-6-sol / gpt-6-luna
Fixed a bug in image encoding that degraded image understanding in GPT-6 Sol and GPT-6 Luna. This update improves results on visual tasks in the API and Codex, including computer use. If your use cases involve image inputs, we recommend rerunning your evaluations and retrying workflows affected by the issue.
公式の更新履歴を見る ↗Feature / gpt-6-sol / gpt-6-luna / v1/responses / v1/chat/completions
Released GPT-6 Sol (gpt-6-sol) and GPT-6 Luna (gpt-6-luna). These reasoning models accept text and image inputs and generate text through the Responses and Chat Completions APIs. Standard pricing per 1M tokens for prompts with up to 272K input tokens: GPT-6 Sol: $2 input, $0.20 cached input, and $10 output. GPT-6 Luna: $0.10 input, $0.01 cached input, and $0.50 output. Compare capabilities in the model catalog, and see pricing for cache writes, longer prompts, and other processing tiers.

Added API key creation governance controls at the organization and project levels. Administrators can allow only service-account keys, allow only user-owned project keys, or disable all new API key creation. Organization restrictions take precedence over project settings, and existing API keys are unaffected. See production best practices for details.
公式の更新履歴を見る ↗Feature
Released the Agents API in public beta. Build agents with a managed Codex harness while OpenAI handles session orchestration, context compaction, and recovery. Use durable sessions to continue work across turns, stream progress, and connect your own tools and MCP servers. Run agents in OpenAI-hosted sandboxes or connect a sandbox from your own infrastructure or a supported provider. Start with the Agents API quickstart.

You can now set expiration dates when creating project API keys. Administrators can also enforce a maximum key lifetime at the organization or project level in Platform settings, requiring newly created keys to expire within the configured limit. See production best practices for guidance on key expiration and rotation.
公式の更新履歴を見る ↗Feature / gpt-live-1 / v1/live/sessions
GPT-Live-1 is now generally available in the API. Build full-duplex voice conversations that can continue while a backend model or agent handles reasoning and tools. Use Responses delegation with an OpenAI model, or client delegation to connect your own backend. Voice sessions cost $0.05 per minute, billed per second; backend model and tool usage is charged separately. Start with GPT-Live, prompting, and migration guidance. See pricing for details.

Voice sessions cost $0.05 per minute, billed per second; backend model and tool usage is charged separately. Start with GPT-Live, prompting, and migration guidance. See pricing for details.
公式の更新履歴を見る ↗Feature / gpt-image-2.5-sunburst / gpt-image-2.5-flare / v1/images / v1/responses
Released GPT Image 2.5 Sunburst and GPT Image 2.5 Flare for image generation and editing through the Image API and the Responses API image generation tool. Use Sunburst for workflows where editing precision matters most, or Flare for fast, high-quality everyday image generation. Both models support the new xhigh and max quality settings and use GPT Image 2 token rates. See the image generation guide and pricing.
公式の更新履歴を見る ↗Feature / v1/responses
Prompt Cache Diagnostics is now generally available in the Responses API for GPT-5.6 and later supported models. Compare cache reuse against a previous response, identify reasons for cache misses, and follow troubleshooting guidance to improve cache reuse.
公式の更新履歴を見る ↗Feature / gpt-rosalind-research
GPT-Rosalind (gpt-rosalind-research) is now generally available through the trusted-access program for approved internal life sciences research. Standard pricing is $5 per 1M input tokens, $0.50 per 1M cached input tokens, and $25 per 1M output tokens. Billing begins on October 5, 2026. See pricing for details.
